Bondloc B270 Studlock is a permanent green coloured general-purpose adhesive for permanent threaded assemblies. B270 locks studs up to 1in, sealing against leakage and corrosion. It is chemical resistant, resisting fuels, lubricants and most industrial liquids and gases.
It eliminates double nutting and/or welding of critical assemblies. It also permits reduced casting thickness and ultimate lightness, reduced assembly stress and eliminates cracked castings due to interference fit stresses.
